DT Swiss Arc 1400 Dicut 85 Carbon Disc front wheel

Take the lead of your next ride with the fast and controllable wheels

The lead over your friends and rivals won’t just be given out to you. You will have to train hard to reach your goal. Helping you on your quest is the third generation of the benchmark ARC 1400 DICUT now ideally suiting wider tires. With a unique v-shape that allows for a wider inner width without compromising aerodynamics. The ARC 1400 DICUT 38, with its 38 mm high rim remains the ideal climbing wheelset for blasting through the iconic climbs on your bucket list. Combined with top-of-the-line 240 DICUT hub with Ratchet EXP system and DT aerocomp II spokes, will help you take the lead in your next ride. Take the lead of the bike leg: when a fast setup is needed for all out speed at your next triathlon or time trial. Ideally suiting both 28 and 25 mm tires, mount AERO 111 26 mm for the best aero performance.

Greater internal rim width
The 22 mm internal rim width is ideal for mounting wide tyres (28 to 30 mm) for greater comfort.

V-shaped rim
The newly designed rim shape has a smaller front surface area to reduce basic aerodynamic drag.

Aero spokes
The latest generation DT Aerocomp II spokes guarantee low rotational and translational resistance.

Hub
The 240 DICUT hubs offer all the reliability of the Ratchet EXP system.

Now lighter for faster climbs
With a rim height of 38 mm and an internal width of 20 mm less, this set of climbing wheels guarantees reduced weight to overcome even the steepest gradients.

Technologies

Aero+
Translational drag is the aerodynamic force that slows the cyclist down in the direction of travel. This force depends on the cyclist's frontal impact surface (75%), the road bike and its components (25%), and speed. To minimise translational resistance, the impact surface of the cyclist/bike combination must be limited by optimising its aerodynamics as much as possible. If you want to go faster, it is essential to reduce the aerodynamic resistance of the cyclist/bike combination, as the force increases proportionally to the square of the speed. From 15 km/h upwards, aerodynamic drag is the greatest resistance that the cyclist has to overcome. The front wheel plays a key role, accounting for 8% of total drag.

Ratchet EXP technology
Much more than optimised reliability. The fusion of the sprocket and threaded ring into a single piece is a major advantage, as it reduces the number of components in the system. The use of a single cylindrical spring ensures faster engagement, thus improving reliability. The integration of the bearing into the threaded ring maximises the distance between the bearings. This increased spacing provides greater support for the axle and reduces deflection, while optimising bearing protection and durability.

Tubeless technology
All DT Swiss wheels are compatible with tubeless technology, and ASM versions are designed for tubeless systems, equipped with tubeless tape and valves. Tubeless tyres offer several advantages over the traditional combination of inner tube and tyre: the tyre can be inflated to lower pressure levels without the risk of pinching (so-called “snake bite” punctures) and with superior grip. The lower pressure offers greater riding comfort and the absence of an inner tube eliminates friction between the inner tube and the tyre, resulting in reduced rolling resistance on terrain and obstacles. The use of a sealant for tubeless systems allows the tyre to self-seal punctures and small cuts. This is a great advantage for those who enjoy long rides and who, in the event of a problem, would find themselves several kilometres from the nearest repair shop.

Bearing technology
DT Swiss hubs are designed to function optimally once mounted on the bicycle. To this end, the tightening torque generated by the wheel mounting system must be taken into account when manufacturing the hubs.
